Hello again
its specifically the
PANASONIC MINAS A4 200W DRIVER
MADDT1207
that interests me.
90.1v
/\ not the 003 extension - as thats digital only - not the 'p' as that position only
I think its perfect for my little table that runs nema 23's at the moment.

I just WANT - don't need to fit a servo system, bit stoopid really.

I can't find any info to suggest it willwork 5v
maybe it will though?

I can not find a manual, just some data sheets that are not too specific.
The I/O will almost certainly be 24v as is the case with most industrial type drives.
The sheet I found suggested the pulse/direction was line driver which would suggest that it is looking for a 5v differential input, ie 5v differential Step/Dir. That is by far the most common Step/Dir setup in industrial drives although I have seen some such as Baldor having 24v Step/Dir.

aha, think i have it
the  encoder feed from the motors to the drive is 24 volts - thats the confusing part?
step and direction pulse train is always 5 volts
driver sends upto 90 volts to the drive side of the motors.

break out board wants 24 volts to stabilise limit switches - spindle control - e-stop, this is opto isolated sheilded  away from the 5v
usb feed from the pc to the input on the drive, thus making it a cleaner signal? so you don't get any noise from the limits - e-stop - spindle interfering with the stepp and direction for the drive .............ahhhhhhhhhhh

so i need 3 motors - some wire, 3 drivers, one of them bobs, a 24v psu.
3 motor mounts with a 70mm pcd, some couplers 11mm to 1/4''
bolton
why am I doing this?
can I send you a drawing and you mill me some mountings £ price please

I am thinking I can 'almost' have a laminated 3 times 15mm plate alloy affair = 45mm motor mount

yay,
those who wait...........

blam, that is almost £53 quid each -delivered!!!

prAy tell Mr .Hood I have the choise of purchasing the motors with two differing encoders
P- incremental pulse counts = 2500P/r  resolution 10000 - wires 5
or
S Absolute -pulse counts =  17 bit - resolution 131072 - wires 7

do I simply get the higher resolutoin. -do I need to be running mach4 with a ethernet 100mbps connection
are there any network mach 3 break out baords with gigabit network 1000 whatsname speed

It will all depend on the drives as to what they can handle. Assuming they can handle both then it wouldnt really matter too much.

Hello Again Mr. Hood,
I has just dawned on me why there isn't so much servo talk here on machsupport - Is it simply due to servo systems being 220volt, and in the \u\sa its 110v - so If you like its 'LIKE' them 'LIKE running 3 phase 415?

hmmm, no wonder there is very little info to glean,
Thank yoiu

p.s. its information 'like' do I need to run limit switching with a servo system that has positioning encoders?
do 'most' of them have programmable limits - simply set the table size if you like, similar to sheetcam.

In the USA I believe they have 2 lives of 110v and a neutral, so they can get 220v by using the 2 lives rather than a live and neutral as we do in the UK.

You should always have limit switches, if you have absolute encoders and they are battery backed up then it may be possible to do without home switches. That would depend on the drives and also whether you could communicate the home position to Mach effectively.

ok so page 98............
yokogowa electric?
usb feed from computer at 5v
5v power supply for pulse train  out put - that to me means step and direction?
cw + from plc/breakout boardto pin 4
cw minus to pin 3
ccw plus to pin 6
ccw - to pin 5
- 5v opto isolated from 24 v
------------------------------------
then using a 24 volt power supply, into a 24 volt breakout board go
e stop pin 7
alarm
limit switches

is it that simple?

24 v power supply to breakout board

Ok it is late here so dont want to read through the post again to see what you have. If I recall though your board has line driver output.
If that is the case then you would connect as in Pg 84 PI 1 (1)
